Health booth

ABSTRACT

A health booth ( 10 ) includes a shell ( 20 ), at least one chair ( 30 ), and at least one measurement arrangement ( 31, 32, 33, 34 ) for measuring data relative to the health of a user. The booth includes: a determination apparatus ( 41 - 50 ) for determining, at the time of taking a measurement, at least one condition under which said measurement is taken; and a storage device for storing the measurement results in a data structure together with said condition.

BACKGROUND OF THE INVENTION

The invention relates to a health booth for obtaining measurements establishing the health of a user or of a population.

Establishing a person's health requires a number of measurements (weight, heart rate, temperature, etc.) to be taken under the supervision of medical personnel.

These measurements must sometimes be repeated at regular intervals to track how they change over time.

The obligatory presence of health personnel causes a number of problems.

First of all, it is clear that in developing countries, where the density of health personnel is low, it is difficult to conduct a health campaign, especially in an emergency, where there is an epidemiological risk present.

In other regions, the main impediment to health screening individually or collectively on a large scale is the relatively high cost of the presence of the above-mentioned health personnel.

To limit the above-mentioned problems, there are known, in particular from the document U.S. Pat. No. 5,544,649, “telemedicine” methods in which patients communicate with a doctor or other health personnel remotely, via a telecommunications network, the patients themselves effecting a number of measurements that are sent to the doctor via the network.

It should be noted that those solutions are not really satisfactory since they require the presence of health personnel when the measurements are taken, even though at a remote location.

One solution that springs naturally to mind would be to have patients take the measurements themselves, for example at home, with no contact with medical personnel, and then send the measurements to a remote center for subsequent processing.

However, it is difficult to envisage such a procedure since it is known that medical measurements are strongly linked to the conditions under which they are taken, in particular the patient's stress or fatigue and the meteorological, sound, and light environment at the time of taking the measurements.

In other words, if this information is not known, the measurements cannot be used by a doctor with sufficient reliability.

OBJECT AND SUMMARY OF THE INVENTION

The present invention mainly aims to solve the above drawbacks.

To this end, the invention relates to a health booth including a shell, at least one chair, and at least one measurement means for measuring data relative to the health of a user. This booth includes:

-   -   determination means for determining, at the time of taking a         measurement, at least one condition under which the measurement         is taken; and     -   storage means for storing the measurement results in a data         structure together with said condition.

In the context of the invention, the expression “health booth” must be interpreted broadly, and designates any space defined by a shell in which users can themselves make a number of measurements relating to their health without the presence of medical personnel being necessary, even at a remote location.

A health booth in the sense of the invention can be transportable, for example, so that it can be installed temporarily at a given location. Health booths in the context of the invention can in particular consist of mobile homes or vehicles of the type used for collecting blood from donors.

A health booth in the context of the invention can also consist of a fixed structure intended to be installed in places through which people pass, for example airports or hotels.

The difference between the health booths of the invention and the previously-known installations lies in the fact that the environmental conditions, at the time of taking a measurement, are stored in a data structure together with the measurement results.

Thus, when health personnel is informed of the measurement results, said personnel is fully aware of the conditions under which said measurements were taken, thus making said data fully useable.

In an embodiment of the invention, said determination means are suitable for measuring at least one data item from among the following:

-   -   a position of the user;     -   the temperature inside and/or outside the shell;     -   a sound level inside and/or outside the shell;     -   a humidity content inside and/or outside the shell; and     -   a brightness level inside and/or outside the shell.

Indeed, it is known that the following data items are necessary for good interpretation of at least one medical measurement.

In particular, the position of the user greatly influences the measured blood pressure. It is recommended that blood pressure is measured in a seated position, the arm resting on a table and the inflatable cuff positioned on that arm at the same level as the heart.

It is also known that the measured blood pressure is greatly influenced by events liable to increase it, in particular cold, noise, and physical effort.

It is also known that environmental stress and hyperthermia greatly influence the heart rate.

It is also known that the blood oxygen saturation level is greatly influenced by the ambient light level and by the relative humidity to which the skin is exposed.

Generally speaking, the means for measuring the above data can consist of appropriate sensors combined with calculation means.

For example, to be sure that a user is seated comfortably when taking blood pressure, it can be envisaged to use pressure sensors placed on the seat and on the backrest of the chair in the health booth.

To be sure that the user's arm is resting in an appropriate position, sensors can be placed on an armrest of the chair in the health booth.

A thermometer, a microphone, a hygrometer, and a photo-electric cell can be used to measure the temperature, sound level, relative humidity and brightness inside or outside the shell.

In a preferred embodiment, the health booth includes means for verifying that health measurements are taken when a given condition satisfies at least one predetermined criterion.

This feature means that health measurements can be effected under optimum conditions.

For example, it can be decided not to measure blood pressure until the patient has been seated for at least five minutes.

In one embodiment of the invention, these control means are optional because it can be important, especially after a natural disaster, to take large numbers of health measurements, in order to implement emergency measures, even though the measurement conditions are below optimum.

In other embodiments, the control means can be used systematically.

In a preferred embodiment, the shell of the health booth of the invention includes at least one opening for linking the health booth to at least one other health booth.

This forms a “hospital” consisting of interconnected health booths.

This feature proves particularly advantageous for guaranteeing certain predetermined conditions in a number of health booths installed in the same area.

For example, in a particularly hot region, it is easier to reduce the temperature in a number of health booths that communicate with each other than in the same number of individual health booths.

The health booth according to the invention includes means for sending the data structure to a remote center.

Advantageously, this feature makes it easier to collect the data structures as recorded in a plurality of health booths or in a hospital within the meaning of the invention.

In a particular embodiment, the health booth of the invention includes power supply means.

These power supply means can use solar energy, for example, or open and/or closed thermodynamic cycles. They are used to supply the health booth with electricity and to regulate the temperature inside the health booth.

For more details of such power supply means, the person skilled in the art can refer to the patent documents FR 2 462 584 and FR 2 588 645.

DETAILED DESCRIPTION OF ONE EMBODIMENT

FIG. 1 represents a health booth 10 conforming to one particular embodiment of the invention.

The main components of the health booth 10 are a shell 20 and a chair 30.

In a different embodiment of the invention, the health booth 10 can contain a number of chairs 30. The health booth 10 includes a number of means for measuring data related to a user's health.

In the embodiment described here, these measuring means comprise:

-   -   an inflatable cuff 31 placed on the user's arm to measure their         blood pressure, this cuff further including heart rate sensors,         not shown;     -   scales 32 for measuring the user's weight when seated on the         chair 30;     -   a height gauge 33 for measuring the user's height in a standing         position; and     -   an oximeter 34 for measuring the user's blood oxygen saturation         level.

In the embodiment described here, the oximeter 34 is fixed to the end of one armrest 35 of the chair 30.

According to the invention, the health booth 10 includes a number of sensors for determining the conditions under which the health measurements are taken.

In the embodiment described here, these sensors comprise:

-   -   a sensor 41 for determining whether the door 25 of the health         booth is open or closed;     -   a pressure sensor 42 on the seat of the chair 30 for detecting         whether the user is seated on the chair;     -   a pressure sensor 43 in the back rest of the chair 30 for         determining whether the user is sitting back in the chair 30;     -   two sensors 44 on a footrest attached to the chair 30 for         detecting whether the user has both feet resting on the         footrest;     -   two sensors 45 disposed under the height gauge 33 to determine         whether the user is correctly placed when measuring their height         with the height gauge 33 or measuring their blood pressure in         the standing position using the inflatable cuff 31;     -   a thermometer 46 for measuring the temperature outside the shell         20;     -   a thermometer 47 for measuring the temperature inside the shell         20;     -   a hygrometer 48 for measuring the relative humidity outside the         shell 20;     -   a hygrometer 53 for measuring the relative humidity inside the         shell 20;     -   a microphone 50 for measuring the sound level inside the health         booth 10; and     -   a photo-electric cell 54 for measuring the brightness level         outside the shell 20.

In the embodiment described here, the health booth 10 includes a lamp 55 for producing a predetermined brightness inside the health booth 10 so that the brightness inside the shell 20 is the optimum for taking health measurements with the door 25 closed.

In accordance with the invention, when a health measurement is taken, the conditions under which it was taken are stored in a data structure together with the measurement results.

In the example described here, this data structure is a computer file.

The health booth 10 includes a computer 60 to which each of the sensors and measuring instruments referred to above is connected, as shown in FIG. 2.

This computer 60 is adapted to generate a file as shown in Appendix 1 and to send that file to a remote center 100 via a telecommunications network R.

In the example described here, the computer 100 is installed within the thickness of the shell 20.

In the particular embodiment described here, the computer 60 and all the electrical equipment of the health booth 10 are supplied with power by a motor 20 placed within the thickness of the shell 20 and connected to a solar panel 71.

The solar panel 71 heats a fluid injected into the motor 70 via a pipe 72, the motor using this heat energy to generate the electrical power supply necessary for the electric instruments of the health booth 10 to operate and to effect cooling by compressing another fluid.

The motor 70 is therefore adapted in particular to regulate the temperature inside the health booth 20 by injecting warm air into it via a grille 72.

The health booth 10 described here also includes a ventilation grille 29 and a touch-sensitive screen 80 for interaction with the user.

There is described below a scenario for use of the health booth 10 to establish a health file for a user in the form shown in Appendix 1.

The user enters the health booth 10 via the door 25, leaving the door open behind them, which is detected by the sensor 41.

The touch-sensitive screen 80 shows a message prompting the user to enter their age. In this embodiment the health measurements cannot begin until this data item is entered. The age is then stored in the Appendix 1 file.

Once the age of the user has been entered, a message on the touch-sensitive screen prompts the user to measure their height using the height gauge 33.

Until the user places their feet correctly on the marks aligned with the sensors 45, a message prompts them to assume a new position.

The height is then stored in the Appendix 1 file.

Once their height has been measured, the user is prompted to remain standing on the above-mentioned marks to measure their blood pressure in the standing position. Sensors in the cuff 31 detect that it is positioned correctly.

When this has been detected, the computer 60 starts a counter and takes two blood pressure measurements, after one minute and after five minutes, respectively, and the respective results 11.8 and 11.6 of these measurements are stored in the Appendix 1 file.

The user is then prompted to sit on the chair 30.

Before measuring their weight, it is verified that the user is seated (sensor 42 activated) with both feet placed on the footrest (position of the feet detected by the sensors 44).

If so, the weight is measured by the scales 32 and stored in the Appendix 1 file (81 kg).

A message on the touch-sensitive screen 80 then prompts the user to put the blood pressure cuff 31 on again to measure their blood pressure in the seated position.

In the embodiment described here, to optimize the blood pressure measurement, the user is required to be seated (this is detected by the sensor 42) and sitting back in the chair 30 (this is detected by the sensor 43) with their arm resting on the armrest 35 (this is detected by two position sensors 83).

When the computer 60 registers this position, it requests the user to wait for five minutes.

In this example, when the five minute delay expires, the user has unfortunately removed their arm from the armrest 35.

The measured blood pressure 12.7 is stored in the data structure, with information representing the fact that the user was seated and sitting back but that their arm was not positioned on the armrest.

At the time of measuring the user's heart rate using the blood pressure cuff 31, the microphone detects a very high noise level, namely a noise level of 120 dB caused by a jackhammer.

It is known that noise level strongly impacts on the heart rate.

Consequently, the touch-sensitive screen 80 prompts the user to close the door 25, which is detected automatically by the sensor 41.

A noise level of 50 dB is then measured inside the health booth 10.

When the door 25 is closed, the lamp 55 produces an optimum brightness level of 120 cd.

When the measurement is taken the temperature inside the health booth is 19° C.

The touch-sensitive screen 80 prompts the user to wait for one minute and a heart rate of 60 bpm is then stored in the Appendix 1 file.

Finally, a message prompts the user to measure their blood oxygen saturation by placing their index finger in the oximeter 34 positioned at the end of the armrest 35.

The measured brightness (120 cd) and relative humidity (4%) are stored with the result of this SpO₂ blood oxygen saturation measurement: 95%.

The computer 60 then sends the file automatically to a remote center 100 via a telecommunications network R.

In the embodiment described here, the health booth 10 has two facing removable doors 90.

As shown in FIG. 3, these doors enable a “hospital” to be produced by positioning two health booths side by side and removing the removable doors 90 to create an airlock passage between the two health booths.

In a preferred embodiment, the health booths 10 in this particular arrangement are connected together by an air-tight seal 92.
